Synthesis and hydrogenation application of Pt-Pd bimetallic nanocatalysts stabilized by macrocycle-modified dendrimer.

ABSTRACT: Different generations of poly(propylene imine) (G _n -PPI) terminated with N-containing 15-membered triolefinic macrocycle (G _n M) (n = 2, 3, 4, 5) were prepared. The bimetallic nanoparticle catalysts G _n M-(Pt _x /Pd_10-x ) (x = 0, 3, 5, 7, 10) were prepared by the synchronous ligand-exchange reaction between G _n M and the complexes of Pt(PPh₃)₄ and Pd(PPh₃)₄. The structure and catalytic properties of G _n M-(Pt _x /Pd_10-x ) were characterized via Fourier transform infrared spectroscopy, ¹H nuclear magnetic resonance spectroscopy, X-ray diffraction, X-ray photoelectr
